I just want him to explain how someone is half Catholic or half Jewish.
He might have been using a sort of shorthand to suggest that one of his parents is Catholic, and the other Jewish.
But that's just a guess on my part.
If he had converted to Christianly rather then Catholicism, there would be no question about half and half.
(I know I will get flamed for this response and I will ignore them as I have in the past. I am a Bible believing, born again Christian who firmly believes that there is a strong fundamental difference between Catholicism and genuine Christianity.)
Flame away …
Love the smell of dissenting emails in the morning!
One parent is a nonpracticing Catholic and the other a nonpracticing Jew, and he is totally confused?
